The annual festival stems from a mysterious crash northwest of Roswell in 1947. The Army initially said it was a UFO crash, but quickly backed off that report. The Pentagon has since said it was a top-secret balloon crash, but UFO enthusiasts don''t believe that story, which gives rise to what has become known as the 'Roswell Incident'.
